The WWSL

The WWSL Bridge List is intended to include every bridge which the Western Washington Short Line owns or maintains, including railway bridges, grade separations and other bridges in which the WWSL has an interest or obligation. Bridges not owned or maintained by the WWSL but used by WWSL locomotives are generally shown.

The information contained herein is as complete and up to date as limited space permits, but it is not a record nor an officially authorized index to the records, and it must not be relied on in any matter of importance.

All users of the list are requested to inform the Maintenance of Way Department of errors and omissions.
